Title: Vehicle tyre wear indicator - with coloured rubber inserts or continuous band in bottom of tread grooves
Inventor: SCHNELL HEINZ
IPC: B60C11/24
Filed: 1975-08-08
Abstract: The tyre tread is fitted with coloured indicators (7) in the bottom of the tread grooves.

Title: Flexible support esp. for reactor pressure vessel - comprises group of columns with high slenderness ratio in one direction
Inventor: SKOCDOPOLE HERBERT DIPL ING
IPC: F22B37/24

Abstract: A resilient support for power plants esp. reactor pressure vessels, steam generators and pumps of a pressurised water reactor comprises a number of identical struts arranged one behind another (i.e. acting in parallel) in the direction of resilience. The strut cross-section is pref. rectangular, with a side ratio of 1:1-1:2. The buckling length may be reduced by connecting them together, esp. at the mid-point of the column length. The overall envelope of the cross-section of a group of struts is pref. approximately square. Low bending resistance in the desired direction, e.g. radially in the example of a reactor pressure vessel illustrated, is combined with high transverse (circumferential) resistance.

Title: Pumped storage hydroelectric generators starter - uses asynchronous machine with variable frequency supply run as motor with rotor control
Inventor: ENDO KENJI DIPL ING
IPC: H02P1/58
Filed: 1976-05-24
Abstract: One hydro-electric generator (1) has a coupled asynchronous machine (9). To start the unit in a pumping mode the asynchronous machine is run as a motor from the busbars (17) with rotor control (11). When the motor has reached the required speed, the generator (1) is synchronised onto the bars and the motor switched off. The generator thus runs as a synchronous motor. To start the other sets (2, 3, 4) the motor is employed as an asynchronous generator with frequency control (15) on its rotor. It thus delivers variable frequency, starting at a low value, to the incoming machine (2, 3 or 4) to accelerate it up to full speed for synchronising. During the initial change over the asynchronous motor may be run as a synchronous induction motor by supplying d.c. (13) to its rotor.

Title: Measurement of liq. level in container - uses float with magnetic follower in gas filled tube defining end point of measured optical path
IPC: G01F23/292
Filed: 1976-07-08
Abstract: The appts. for determining the level of liquid in a container includes a vertical gas filled tube provided in the container. The tube is surrounded by a magnetic float. A magnetic follower in the tube follows the vertical position of the magnet float, and serves as the termination point of an optical measuring path between a light source and a detector. An optical reference path also extends from the light source to a second mirror which may be mounted at a fixed point in the container kor on the opposite side of the follower. The system incorporates means for determining the difference in propagation time of light in the two optical paths.

Title: Butt-welding hollow thermoplastic profile - by heating the ends circumferentially, pressing contact faces together and pulling them slightly apart
Inventor: ECKARDT PETER DIPL CHEM DR
IPC: B29C65/10
Filed: 1976-07-23
Abstract: Thermoplastics hollow profiles are butt-welded together by heating the entire circumference of frontal faces to be welded; fusing them whilst pressing them together; and then very slightly pulling them apart. Before the welding step, a hollow body which does not adhere to the melting plastics, and whose outer dia. is a little smaller than the inner dia. of the profiles to be welded, is introduced into both profile ends. A blocking device is inserted into one of the hollow profiles whilst a closure with a flexible hose is fitted into the other profile. After the 2 profiles have been pushed together, a reduced pressure is party or permanently generated inside the profiles. After the welded-together profiles have been pulled slightly apart, a slight superpressure is opt. set. up. Used in butt-welding of thermplastics pipes and tubes. Formation of circumferential welding rims or thick seams is minimised.

Title: Air and fuel metering system for IC engines - with rotary vane valve in air inlet controlling fuel supply to ensure proportion is related to engine demand
Inventor: WESSEL WOLF ING GRAD
IPC: G01F1/28
Filed: 1976-08-14
Abstract: The air volume meter for injector systems in I.C. engines consists of a rotary vane valve in the shape of a segment of a cylinder (6) which is suspended in a bearing running at right-angles to a throttle valve (4) air inlet (2). The vane swings in a chamber formed from a semicircular component having an inlet and outlet port (9, 10). The outlet port aperture opening is determined by the position of the vane. The boring through the vane carries a bush in which is cut a control slit. The control slit opening is varied according to the setting of the vane. Fuel is fed to the control slit so that a metered a mount can flow through a delivery channel (45) to the edge of the vane (46). Thus the metered amount of fuel is proportional to the air demand of the engine.

Title: Printer for desk computer - with hammer actuated by spring when permanent magnet field is cancelled
Inventor: NOZAKI MINEO
IPC: B41J9/36
Filed: 1977-01-14
Abstract: The printer for a desk computer has a head (4a) with a plastic hammer (4) tensioned by a spring (6) the other end of which is anchored on the pole of the stationary electromagnet (2a). The attraction of the permanent magnet (1) brings it into contact with a teflon (RTM) damper and stresses the spring whose stored energy is used for driving the hammer when the electromagnet is excited. The spring propels then the head against the type wheel (10) to print a character. The assembly has a damping member the same area as the electromagnetic and these are broad enough to cover several hammer head positions.
